Winemaking agents in rosé sparkling wines: evolution of phenolic composition and stability of tannins

Rosé sparkling wines require special elaboration methods that ensure their quality and color stability during aging in bottle. The objective of this work was to evaluate the effect of the addition of different concentrations of gum arabic and tannin in Brazilian rosé sparkling wines elaborated by the Traditional method (cv. Cabernet Sauvignon) and their impact on the phenolic composition during aging in bottle.

Influence of the storage condition on physicochemical characteristics of red wines from São Francisco Valley, Brazil

In the São Francisco Valley, Northeast of Brazil, tropical wines have been produced thirty years ago. Vines can produce twice a year and wine stability can change according to the harvest date. Normally wines elaborated from grapes harvested between November-December have a fast evolution, while wines from grapes harvested between June-July can have greater stability.

Varietal grapes juice a productive choice for the development and environmental protection of marginal wine-growing areas

Rosciola is an antique red grape variety in the Lazio region (Italy) in the area between the Simbruini mountains and the high valley of Aniene. The name “Rosciola” is probably due to the light red color that the skin berries have to maturity. The oenological aspect was observed and evaluated over various vintages (Ciolfi G. et al., 2009).

From science to farmers: VITIROOT shiny app for grapevine rootstock recommendation

The choice of grapevine rootstock remains a critical decision in vineyard establishment, as it is heavily influenced by a complex interplay of factors, including agronomic needs, productivity desires, soil type, climate variability, vine resilience, and adaptability to specific environmental conditions and enological goals.

A Pilot Network of experimental vineyards in Valle d’Itria: An innovative participatory research infrastructure for climate monitoring and viticultural demonstration

The viticultural landscape of Valle d’Itria (Apulia, Southern Italy), historically characterized by high-biodiversity native white varieties and dry-stone architecture, including the typical «Trulli», has suffered a drastic reduction over the last century.
